PURPOSE: Construct / simulate a clamp and work circuit and determinte the settings of all pressure control valves.
PROCEDURE
1. Draw the following
circuit in Automation Studio;
SPECIFICATIONS FOR BOTH CYLINDERS:
BORE: 50 mm
ROD DIA: 25 mm
FRICTION FORCE: 100 N
2. Calculate the
required pressure at each actuator assuming the following:
Maximum clamp force (horizontal cylinder): 4KN
Minimum work force (vertical cylinder): 20KN
3. Set the pressure
control valves 10 bar above required pressures and 10 bar apart;
4. Simulate the
circuit;
5. Measure and
record the pressures on the guages shown on the diagram;
6. Determine the
following:
Relief Valve Setting
____________
Pressure Reducing Valve Setting:
____________
Sequence Valve Setting (work cylinder) ____________
Sequence Valve Setting (clamp cylinder) ____________
Requirements for the electric motor as indicated;
Horsepower @ .85 Efficiency
____________
Power Requirements in kilow-watts
____________
7. Submit a formal
written report by next class period.
